Destati and all it’s versions truly is my favorite piece of music of all time. No really. The only piece of music that ties for first place with Destati, for me, is orchestral versions of One Winged Angel. Two amazing composers, two amazing songs.
This is "Destati" from ReMind, not Dive into the Heart. In fact, the Dive into the Heart music its called Destati, too. This one is just the boss battle version (Darkside), and the third part of KH1 Dive into the Heart world
We use other words to differentiate them which makes them either easier or harder to find based on your perspective, in my opinion if something is just titled Destati then it should be each part of the same song compiled into the same place like a certain KH 1 video titled "The Beginning." And if they're named differently it should just be the one specific segment of the song of course.
Hence why third inception is added, makes it easier to determine which version it is. Like how Simple and Clean is Simple and Clean and at then end of KH1 we call it Simple and Clean after the battle, easy to spot.
it's titled correctly. if you play "Dive into the Heart - Destati- Third Inception" from the KH3 OST and skip to 4:45 you'll hear this. it was reused for the darkside fight in Re:Mind but it's originally from base KH3
